      • parseBoolean

        public static boolean parseBoolean​(char[] text,
                                   int offset,
                                   int length,
                                   boolean defaultValue)
        Parses a char[] representation of a boolean value to boolean.
        Returns:
        true iff the sequence of chars is "true", false iff the sequence of chars is "false" or the provided default value iff either text is null or length == 0.
        Throws:
        java.lang.IllegalArgumentException - if the string cannot be parsed to boolean.
